FOLDABLE ROOF-BRACKET.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed July 14, 1917. Serial No. 180,650.

To all whom it may concern:

Be it known that EDWARD H. CHAPPUIS, a citizen of the United States, residin at Marysville, in the county of Yuba and tate of California, has invented certain new and useful Improvements in Foldable Roof- Brackets, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to roof brackets, and particularly to foldable roof brackets.

The general object of the invention is to provide a roof bracket which is so constructed that it may be folded into a very compact form, for transportation, storage or shipment.

A further object is to provide a roof bracket with a detachable platform or seat and in this connection to so form the seat that it may be folded upon itself and incase or partially surround the frame members of the bracket when they are folded.

A further object is to rovide the seat with a plurality of hand hoihs so that it may be conveniently shifted and also so that it may be readily carried with the frame sections or base sections disposed within the folded seat.

Still another object is to provide a roof bracket wherein the base consists of longitudinally extending members connected to each other so that they may be folded against each other or laterally spread, and provide means whereby when the base sections are laterally spread they will have a downward divergent relation.

A further object is to provide means for supporting the seat, this means being adjustable so that the seat or platform may always be supported in a horizontal position without regard to the inclination of the longitudinally extendin base members.

Still another 0 ject is to so construct these base members that they will engage and anchor upon the roof or other structure to which they are applied.

Still another object is to so construct the roof bracket that the parts may be shifted into operative relation or into inoperative relation, without the use of extraneous ap' pliances.

A further object is to provide a device of this character which is very simple, has few parts and these cheaply constructed, but which will be thoroughly effective in use and adapted for use in a large number of different situations.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of my improved bracket;

Fig. 2 is an underside plan view of the seat or platform;

Fig. 3 is a top plan view of the base portion of the bracket with the seat removed;

Fig. 4 is a top plan view of the seat folded, the base portion of the bracket being disposed within the folded seat;

Fig. 5 is a section on the line 55 of Fig. 4.

Referring to these drawings, it will be seen that my improved roof bracket comprises a base COIIIPOSBd of the longitudinally extending metallic bars or strips, designated 10. These bars 10 are angular in cross section to provide an outwardly extending flange 11. This flange is slightly shorter than the members 10 and terminates short of the lower ends of these members. From the lower end of the flange upward for about one-half the length of the strips 10, each flange 11 is provided with upwardly and forwardly extending notches 12 forming a plurality of teeth. The remainder of the flange is plain. Each flange is also formed with a longitudinally extending slot 13.

Connecting the members 10 are the tie braces 14. There are two of these braces disposed in intersecting relation, the braces being pivoted to each other by the rivet 15. It will be seen that this rivet 15 is not disposed at the middle of each brace, but that the lower ends of the braces are longer than the upper ends. The upper ends of the tie braces 14 are pivoted by means of rivets 16 to the respective bars 10, and the lower ends of the braces are longitudinally slotted as at 17, and assing through the lower ends of the members 10 are the rivets 18, which extend into the slots 17 and have sliding en gagement therewith and pivotal engagement therewith. By reason of this construction the longitudinally extending members 10 may be shifted toward each other or spread apart and when spread to the full extent permitted by the braces 14, the rivets 18 will be in the lower ends of the slots 17 and the members 10 will be disposed in divergent relation. The lower ends of the members 10 are downwardly and rearwardly bent or curvedas at 19 and the lower edges of these portions 19 are serrated as at 20 to provide a secure anchorage for the seat supporting frame or base.

Pivotally mounted upon the upper ends of the flanges 11 are the seat supporting bars 21, which are pivoted to the flanges llby means of rivets 22, these bars being disposed upon the outer faces of the flanges 11. Pivotally connected to the bars 21, inwardly of their free ends, are the supporting links 23, and passing through these supporting links are rivets 24, which extend into the slots 13 and have sliding engagement in these slots. Pivoted to the links 23 by means of the rivets 24 are the latches 25, which are formed of sheet metal, the material being bent upon itself for the greater portion of its length to embrace the flanges 11. Each of these latches is provided with the inwardly extending rivet 26, which is engageable in any one of the notches 12.

The seat or platform, which is designated generally 27 is formed in two sections and is preferably of wood, though it may be made of other material, these sections being hinged to each other so that they may be folded over upon each other. These sections are preferably formed each with a pair of elongated hand holes 28 and the sections are connected to each other by strap hinges 29. These strap hinges extend across the entire width of each section and at the meeting ends the strap hinges are angularlybent as at 30, and connected to each other at the extremities of these angularly bent ends by means of the usual pintles, (see Fig. 5).

It will be noted from Fig. 2 that these Strap hinges 29 are disposed in divergent relation to each other and at approximately the same angle to each other as are the members 10 and 21, when the members are spread apart. Attached to the sections of the seat or platform 27 and projecting from its inside face are the resilient latch members 31, These are formed of steel or other suitable resilient material and are angularly bent and attached by screws to the under face of the seat or platform and when the seat or platform is in place on the seat supporting bars 21, these spring latches engage beneath the edges of the bars. The bars "21 are formed with longitudinally extending recesses 32 on the under edges of the bars with which the spring latches 31 are adapted to engage andf'th'us prevent the seat'onplatform from sliding longitudinally'upon' the seat supporting bars 21, the clips at the same time preventing the seat from'heing pulled oif of the bars 21. j

In the practical use of this devicefit is, of

course, placed upon the roof or other strucrare 1n an obvious manner, the serrated ends 19 beingforced into engagement with. the roof or structure and then the links 23 are adjusted to raiseor lower the supporting bars 21 until. they are horizontal, these links 23 heing'locked in their proper position by means of the latches 25, which by gravity drop downward so that the rivets 26 engage in the proper recesses 12. The bars 21 are thus locked against any further depression so as to support the platform or seat in a horizontal position. The platform or seat may be disposed on the bars 21 prior to the adjustment of these bars or may be placed thereon afterward. When the seat or platform is put in position, the resilient latches ing structure is folded into a very compact form and because of the fact that the hinges 29 are formed with the angular terminal ends which separate the two sections of the seat from each other when the sections'are folded, it is obvious that the base structure comprising the bars 10, 21 and 23 and allied parts may be disposed between the folded sections in the manner illustrated in Figs. 4 and'5.

For the purpose of holding the sections in folded relation, I mount upon one of the sections a resilient latch 33 which projects outward from the under side of the section and is preferably disposed at the edge of one of the hand holes so that'when the sections are folded together in the manner illustrated in Fig. 5, this latch will project through the corresponding hand hole of the other section and latch the two sections in their parallel or folded relation.

This improved roof bracket is adapted to be used by carpenters, shinglers, painters, roofers'and in many'other different situations and is particularly convenient, because it may be folded into such compact form and so readily carried, the seat when folded hold in the folded base structure in place.
